rDNA does not fully work on MacOS

[leifeld]

A problem occurs when trying to run rDNA on MacOs 10.5 or 10.6. It is possible to compile, install and load the package in R, but executing the dna.gui() command fails. The error messages are "Apple AWT Java VM was loaded on first thread -- can't start AWT." and "Error in .jnew("dna/Dna") : java.lang.NoClassDefFoundError: dna/Dna". However, DNA (without the R package rDNA) works well on MacOS.

Update: The problem is apparently caused by the fact that java.awt.Color (and possibly other AWT or Swing classes) are loaded in the main thread (i.e., in the very first thread that is started). A possible solution could be to start a new thread for the rest of DNA immediately after starting the main class of DNA (or any class associated with the DNA JAR file).

rDNA is not compatible with DNA 2.0 and needs to be rewritten completely anyway.
